Spleen is a large bean-shaped organ which mainly contains lymphocytes and phagocytes. It acts as a filter of the blood by trapping____ Micro organisms.

Options

A. Tissue fluid borne
B. Blood-borne
C. Water-borne
D. Lymph-borne

Answer

To solve the question regarding the function of the spleen in filtering blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of the Spleen**: The spleen is an important organ in the immune system. It is responsible for filtering blood and removing old or damaged blood cells, as well as pathogens.

2. **Identify the Components of the Spleen**: The spleen contains lymphocytes (a type of white blood cell) and phagocytes (cells that engulf and digest foreign particles). These components play a crucial role in the immune response.

3. **Determine What the Spleen Filters**: The question asks what type of microorganisms the spleen traps as it filters the blood. The options provided are:
- A) Tissue fluid borne
- B) Blood borne
- C) Water borne
- D) Lymph borne

4. **Analyze Each Option**:
- **Tissue fluid borne**: These microorganisms are found in the interstitial fluid and are not primarily filtered by the spleen.
- **Blood borne**: This refers to microorganisms that are present in the bloodstream, which is the primary function of the spleen.
- **Water borne**: These microorganisms are typically found in water sources and are not filtered by the spleen.
- **Lymph borne**: While the spleen does interact with lymphatic fluid, it primarily filters blood.

5. **Select the Correct Answer**: Based on the analysis, the spleen acts as a filter for blood borne microorganisms. Therefore, the correct answer is **B) Blood borne**.

### Final Answer:
The spleen acts as a filter of the blood by trapping **blood borne microorganisms**.
